MULTIPLE COPYING-MACHINE.

Speccation of Letters Patent.

Patented Jan. 10, 1911.

To aZZ whom 'it may concern:

Be it known that I, WILLIAM STABLEFORD, subject of the King of Great Britain, residing at 57 I-Iolborn Viaduct, in the city of London, England, merchant, have invented certain new and useful Improvements Re lating to Multiple Copying-Machines, of which the following is a specification.

My invention relates to improvements in multiple copying machines and more particularly to that type in which means are provided for damping the paper strip on both sides without passing the same through a water bath, thereby enabling the use of a paper of much stronger quality.

My invent-ion has for its object improved damping apparatus and improved means for guiding the paper and collecting the severed portions. According to my inven tion, the water is conveyed to one side of the paper and pressed through the paper to the other side, means being provided whereby the proper degree of dampness may be regu* lated which means are independent of the means for regulating the pressure of the copying rollers.

In the accompanying drawings, Figure 1 is a side elevation of -the machine, Fig. 2 is a section of a portion of the machine, Fig. 3 is a sectional detail view of the paper collecting device, and Fig. 4 is an elevation of the guide for the paper.

I employ a covered roller a which is partially immersed in water contained in a suitable tray Z) which is supported upon rails c iixed to the frame oZ. The paper e from the supply roll f passes over the upper portion of the covered roller a and below a pressure roller g which presses the paper into close contact with the covered roller a and forces some of the water through the paper. The covered roller a and the pressure roller g are carried by a frame h pivoted at h', means being provided for regulating the position of said frame with regard to the water bath, such as the arm z' and quadrant j shown in Fig. 1. In a similar manner, the pressure roller g is mounted in a frame le which may be moved about its pivots 7c on the frame 7L., to or from the paper, and the desired pressure may be applied through the me* dium of springs k2 or by the weight of the frame c and roller g, or by both.

Z is the main copying roller, m is the adjustable copying roller and a is a pressure roller working against the roller Z. These rollers are formed of solid metal covered with vulcanite, rubber, or other suitable material, the main copying roller Z being mounted in fixed bearings and rotated'by means of the handle 0, and the copying roller m being adjustable to and from the iXed roller by a lever m and cam or other suitable mechanism. The ressure rollerla is independently adjustab e to and from the main roller Z by a lever a and cam or other convenient mechanism, and serves to regulate the amount of moisture in the paper according to the quality or quant-ity of the ink on the document to be copied.

The damp paper, after passing through the copying rollers, passes between a pair of rollers p, g, and descends at the end of the machine. At this part instead of having flat guide plates to which damp paper would sometimes cling, I now provide a grid-like guide which may be formed of cords laced vertically, or a vertically ribbed or corrugated plate, or a number of vertically disposed wires, suitably supported. The guide shown on the drawings consists of a bent plate 9" mounted upon the pivoted cutter frame s and wound with cord 7 as clearly shown in Fig: 4.

The paper cutting mechanism, which forms no part of the present application, comprises a pivoted cutter frame s carrying a blade and a sliding cutter Jframe s operated by means vof a handle s2, the cutter frame s being provided with a blade and being mounted in suitable guides s3, s4.

For collecting the severed portions of paper strip as they fall from the cutting mechanism I provide a collecting bar .t which is iXed to the sliding cutter rame s. On operating the cutting mechanism s, S, by the sliding handle s2 the paper e is pressed against the-side of the bar t by a frame u pivotally mounted in connection with the side arms o which are operated by the cutting mechanism by means of the pin o on the sliding cutter frame s and slot o2 in one of the side arms, a spring u being employed to control the motion of the frame a. A depending plate w is iXed to the arms 'v and serves, at the moment of severing, to throw p frame and plate Vdamp paper device for the severed the upper part of the paper over the bar t so that it becomes shown in Fig. 3.

I claim l. In a multiple copying machine, a covered roller, a pivoted frame carrying said roller, adjusting means for said pivoted frame, a pressure roller, a frame carrying said pressure roller pivotally mounted on said pivoted frame, and means imparting the desired pressure, as set forth. A

2. Inamultiple copying machine a guide formed with a grid-like surface guiding the strip to the cutting mechanism, as set forth.

3. The combination of a main copying rol er, means rotating same, an adjustable copying roller, an adjustable pressure roller, a covered roller applying water to one side of a paper strip, means pressing said paper strip against the covered roller thereby forcing the water through said strip, and a gridlike guide for the damp paper, as set forth.

4. The combination with a main copying roller, means rotating same, an adjustable copying roller, an adjustable pressure roller and a paper damping device, of a collecting portions of paper strip comprising a collecting bar, a frame adapted to press the paper against said bar, a plate adapted to throw the upper part of the paper over the bar, and means actuating said as set forth.

5. In a multiple copying machine the combina-tion with a sliding .cutter frame of a collecting device for the severed portions of paper strip comprising a bar fixed to said frame, a pair of pivoted arms actuated by the sliding cutter frame, a frame pivoted to said arms, a spring controlling said frame, and a plate iXed to said arms, as set forth.

6. In a multiple copying machine, a gridlike guide for the damp paper, apivoted cutter frame carrying a blade, a sliding cutter frame carrying a blade, a barl liXed to the sliding cutter frame, a pair of pivoted arms actuated by the sliding cutter frame, a frame pivoted to said arms, a spring controlling said frame, and a plate fixed to said arms, as set forth.

7. In a multiple copying' machine, containing a liquid bath, a damping arranged to be partially submerged in the bath, an adjustable frame carrying the damping roller, and means for drawing a strip of paper over the unsubmerged surface of the damping roller.

8. In a multiple copying machine, means for severing a strip of paper into lengths, means for collecting the severed lengths in` cludinr a collector bar. and a gripping part movabIe relatively thereto, and a plate also movable relatively to thecollector bar to throw the severed lengths over said bar.
